SocketException in HttpClient GET
Hi,
We are trying to solve a very simple problem for *HttpClient4* -- SocketException for HTTP GET. HttpClient4 gets the first "chunk" of data from server (Tomcat-6.0.18) and then the server unexpectedly closes the connection.
We tried the following HttpClient4 versions to fix this but it did not work!
- 4.1-beta1
- 4.1-alpha2
- 4.1-alpha1
- 4.0.3
- 4.0.2
- 4.0.1
The same piece of code works with HttpClient3.
Do you know if HTTP GET has any known bugs for HttpClient4? We could not find any on the internet.
The debug logs report the following:

We are reading the response in the standard way:
StringBuilder sb = new StringBuilder();
try {
BufferedReader br = new BufferedReader(new InputStreamReader(inputStream));
char[] buf = new char[4 * 1024]; // 4Kchar buffer
int len;
while ((len = br.read(buf, 0, buf.length)) != -1) {
sb.append(buf, 0, len);
}
br.close();
} finally {
...
}

There are no known bugs of that kind. If there was any issue with the
GET request the server should have responded with an error status code
such as 400 instead of just dropping connection. So, to me this problem
sounds like a server side issue.

Hi,
We are trying to solve a very simple problem for *HttpClient4* -- SocketException for HTTP GET. HttpClient4 gets the first "chunk" of data from server (Tomcat-6.0.18) and then the server unexpectedly closes the connection.
We tried the following HttpClient4 versions to fix this but it did not work!
- 4.1-beta1
- 4.1-alpha2
- 4.1-alpha1
- 4.0.3
- 4.0.2
- 4.0.1
The same piece of code works with HttpClient3.
Do you know if HTTP GET has any known bugs for HttpClient4? We could not find any on the internet.
